In the paper, it is proven that every object in C(R-GProj) has a specialC(R-Proj)-preenvelope, and then some adjoints in homotopy categoriesrelated to Gorenstein projective modules are given, where C(R-Proj) isthe subcategory of complexes of projective R-modules, and C(R-GProj)is the subcategory of complexes of Gorenstein projective R-modules.
